Copies the text of the field at the specified row and column index into a Android.Database.CharArrayBuffer.

The buffer is populated as follows:

• If the buffer is too small for the value to be copied, then it is automatically resized.
• If the field is of type ICursor.FIELD_TYPE_NULL, then the buffer is set to an empty string.
• If the field is of type ICursor.FIELD_TYPE_STRING, then the buffer is set to the contents of the string.
• If the field is of type ICursor.FIELD_TYPE_INTEGER, then the buffer is set to a string representation of the integer in decimal, obtained by formatting the value with the printf family of functions using format specifier %lld.
• If the field is of type ICursor.FIELD_TYPE_FLOAT, then the buffer is set to a string representation of the floating-point value in decimal, obtained by formatting the value with the printf family of functions using format specifier %g.
• If the field is of type ICursor.FIELD_TYPE_BLOB, then a Android.Database.Sqlite.SQLiteException is thrown.
